SAFETY-RAZOR.

Specification of Letters Patent.

Patented Aug. 24, 1915.

Application filed July 13, 1914. Serial No. 850,565.

To all whom it may concern:

Be it known that I, SAMUEL W. CHARLES, a citizen of the United States,and a resident of the city of Palo Alto, in the county of Santa Clara,State of California, have invented a new and useful Improvement inSafety-Razors, of which the following is a specification.

My invention relates to improvements in safety razors wherein theconjunction of a suitable extension of a razor guard with a similarextension of a razor blade pivotally mounted upon the extension of therazor guard permits the razor blade to be swung away from the guard andhandle; and the object of my invention is to provide an improved safetyrazor wherein the blade may be readily swung away from the guard so thatthe blade and guard may be easily cleaned without removing the blade. 1accomplish this by closed in the drawings forming a part of the presentspecification wherein like characters of reference are used to designatesimilar parts throughout the said specification and drawings, and inwhich Figure 1 is a front view of the safety razor with the bladedisclosed in a closed position ready for use, showing a leaf springsecured to the upper edge of the guard an arranged to engage blade forthe purpose of retaining the said blade in a closed position and theserrated edges of the guard extending below the edge of the razor. Fig.2 is a view similar to Fig. 1 except that the blade is disclosed in anopen position swung awa from the guard and disclosing the manner inwhich the said blade is retained in such position by means of the leafspring which engages one of the rectangular extensions on the saidblade. Fig. 3 is a side elevation of Fig. 1 disclosing the manner inwhich the blade is pivotally and detachably secured to the guard andheld adjacent thereto, and Fig. 4: is an enlarged detailed sectionalview taken on line X-X of Fig. 1 of the drawings in the directionindicated by the arrow, disclosing the manner in which the razor bladeis pivotally and detachably secured to the guard.

Referring to the drawings, the numeral I is used to designate a suitablehandle to the end of which is rigidly secured in any suitable manner,the guard 3.

The numeral 5 is used to indicate a recmeans of the device d1s-' razorblade 9 is pivotally mounted upon the the upper edge of the tangularextension at the upper edge of the said guard 3.

A leaf spring 6 is secured by means of the pins 7 to the upper edge ofthe guard 3 and at right anglesthereto, the end 8 of the leaf spring 6being free to move, the purpose of which will hereinafter be more fullyde scribed.

A razor blade 9 is provided with a rectangular extension 10 which isarranged to coincide with the rectangular extension 5 of the guard 8. Tothe extension 5 of the guard 3, adjacent'to the free end 8 of the leafspring 6, is detachably secured a bolt 12, which is provided with areduced threaded portion 14 adapted to be engaged by a suitable thumbnut 15 on the opposite side of the said extension 5, so that the saidbolt 12 may be rigidly secured to the extension 5 of the guard by meansof the said nut 15. The rectangular extension 10 of the bolt 12, so thatwhen the said blade 9 is in the position illustrated in Fig. 1 of thedrawings, the leaf spring 6 will lie along the upper edge of the razorblade 9 and the extension 10 thereof. The uper edge of the razor blade 9is provided with a shoulder or recessed portion 16, which provides arecess into which a finger may be inserted for the purpose of openingthe blade 9 when the said blade9 is closed, as shown in Fig. l of thedrawings.

The razor is used in the ordinary manner and after shaving the operatormay read ily and easily clean the blade 9 by rotating the same on thebolt 12 secured to the extension 5 of the guard 3, until the said blade9 assumes the position disclosed in Fig. 2 of the drawings. The blade 9is retained in this position by the tension of the free end 8 of theleaf spring 6, which rests against the flat surface of the extension 5,secured to the bolt 12.

By referring to Fig. 1 of the drawings, it will be observed that whenthe razor blade 9 is in a closed position that the leaf spring 6 willengage the upper edge of the said blade 9, while the free end 8 of thesaid leaf spring 6 will engage that portion of the extension 10 beyondthe pivot formed by the bolt 12 and retain the upper edge of the blade 9against the inner edge of the leaf spring 6. The blade 9 may be detachedfor replacing the blade with another one by unscrewing the thumb nut 15from the reduced portion 14 of the bolt 12, the said bolt 12 may then bewithdrawn from the extension 5 of the guard 3 and the razor blade 9removed and another one secured in place thereof. The length of theunthreaded portion of the bolt 12 is slightly greater than the thicknessof the extension 10 of the plate 9 in which case, when the said bolt 12is drawn tightly onto the extension 5 of the guard 3, the razor blade 9will be free to rotate on the said bolt 12 and will be held in positionby means of the tension of the free end 8 of the leaf spring 6.

It is obvious from the foregoing that I have provided a simple, cheapand practical safety razor, wherein the blade may be easily and readilydetached and moved to an open position for cleansing purposes, and havealso provided means whereby the blade will be eifectively retained in anopen or closed position.

Having thus described my invention what I claim as new and desire tosecure by Letters atent is 1. A safety razor comprising a suitablehandle; a guard secured to the handle and having a rectangular extensionon the upper edge thereof; a razor blade having a rectangular extensioncoinciding with the extension on the guard and pivotally mounted upon,the rectangular extension of the guard; and a leaf spring secured to theupper edge of the guard and adapted to engage the upper edge of theextension of the blade.

2. A safety razor comprising a suitable handle; a guard secured tothehandle and having a rectangular extension on the upper edge thereof; arazor blade having a rectangular extension thereon arranged to coincideWith the extension on the guard; a leaf spring secured to the upper edgeof the guard and arranged to engage the upper edge of the blade and theextension thereon and to retain the coincidence of the blade and theguard; and means adapted to de tachably and-pivotally secure the razorto the guard.

3. A safety razor comprising a suitable handle; a guard secured to thehandle and having a rectangular extension on the upper edge; a razorblade having a rectangular extension thereon arranged to coincide withthe extension on the guard; a leaf spring securedto the upper edge ofthe guard and arranged to engage the upper blade and; one of theextensions thereon and to retain the coincidence of the blade and theguard; and a bolt detachably secured to the guard and adapted topivotally engage the blade and retain the said blade on the guard.

4. A safety razor comprising a suitable handle; a guard secured to. thehandle and having a rectangular extension on the upper edge thereof; anda razor blade having a rectangular extension coinciding with theextension on the guard and pivotally mount.- ed within the coincidingextension on the guard.

In Witness whereof I have hereunto set, my signature in the presence oftwo, subscribing witnesses this 6th day of July, 1914 SAMUEL W. CHARLES.Witnesses M. O. Honcns, I G. CHARLES HGDGES.
